For now nope . As I said I am not good with GIMP , but users can make icon themes just like regular icon themes . They need to be in ~/.icons/mate-window-applets/ or global /usr/share/icons/mate-window-applets/ . Then you have to change the theme in dconf on path /org/mate/mate-window-applets/window-buttons/theme . Right now I am porting the project to gnu-autotools so FAQ will be done later when I finish porting it .

I have used icons from Ambiant-mate theme to create the theme for window-buttonshere it is: https://share.riseup.net/#7FLdbq6r4T5kogkb-qo-iA (link will be able only for a week, so if someone miss it - let me know - I'll post new one)It looks like this:You are welcome to use it in your releases =)

In the Mutiny layout, when you maximize a window with the "hide windows decorations" option enabled, there is no way to get the buttons back and so minimize or close the window without using ALT+F10 first.Your applet, provided it could be dynamically activated whenever the current active window is maximized with no decorations, would be an elegant way to work around this problem.

Yes that is why I made it . Maximus is great for maximizing screen space . Combined with the global app menu it is perfect for screens like mine with resollution 1440x900 and lesser . But the only thing that is missing is the obvius 3 buttons witch everyone knows (close,maximize,minimize).So i tried to redo previous applets that did this but failed .Then I came with my own idea. I tried mimicing the existing applets behaviour like if no window is shown hide the buttons. I am now porting it to vala (suspended untill I get a new charger for the laptop). So if it does not work somehow pls pile a bug report on github and I will fix it and push it to master.

@IndiJones76For starters getting support for wm themes , but i found that wm's use xml parser to draw the themes , and gets very complicated for a simple applet . I assure you that I used a very simular method to the other applets of this kind (e.g. xfce4-windowck-plugin and old gnome-window-buttons applet). The only difference is that I use a Gtk.IconTheme to load the pixbuffs . And as for the numix theme it is great , and you should talk directly to brokoli for this or make your own repository .

@Wimpy Yes it is (At least I think so ). I have done some testing and everything should be working properly . The only thing that is missing is translations , but that will be added in later versions .As for package-ing I have made meson build options to disable a certain applet (for people like me that don't like unnecesary things that I don't wan't to be on my pc) , It should be done after meson --prefix /usr build && cd build like so mesonconf/meson configure -D build-*=true/false . By default all are true. If you package it be shure to package the themes since the default ones suck XD .
